title	Parametric urban design: An interactive sketching system for shaping neighborhoods
doi	https://doi.org/10.52842/conf.ecaade.2011.225
source	RESPECTING FRAGILE PLACES [29th eCAADe Conference Proceedings / ISBN 978-9-4912070-1-3], University of Ljubljana, Faculty of Architecture (Slovenia) 21-24 September 2011, pp.225-234
summary	In this paper we show the structure of an urban design parametric system. The system is dynamic and builds an interactive relation with the designer updating the layout and related data at each input change. The responsiveness of the system allows the designer to gain awareness on the qualitative consequences of each design move by comparing a design state with a set of urban indicators and density measures which are automatically calculated along with the geometrical updates.

title	Parametric Form-Based Codes: Incorporation of land-use regulations into Building Information Models
doi	https://doi.org/10.52842/conf.acadia.2011.x.l7j
source	Parametricism (SPC) ACADIA Regional 2011 Conference Proceedings
summary	This project describes investigations into whether parametric modeling using a Building Information Modeling (BIM) platform can represent the provisions and constraints of Form-Based Codes (FBCs). BIM software environments couple 3D modeling with parametric form generation and rich semantics. Further capabilities of an Application Programming Interface that supports Object-Oriented Programming (OOP) results in a very powerful environment for expressing planning and design concepts. While these capabilities were developed under the intention of supporting building design, we hypothesize that they can support planning rules and regulations that are found in FBCs. If our approach is successful, future planning departments will be able to provide architects and urban designers with a FBC that is implemented as a BIM software toolkit, better integrating the planning phase of a project into the building design phase.

title	Sensing digital co-presence and digital identity: Visualizing the Bluetooth landscape of the City of Bath
doi	https://doi.org/10.52842/conf.ecaade.2011.087

summary	The impact of ubiquitous digital technologies on the analysis and synthesis of our urban environment is undoubtedly great. The urban topography is overlaid by an invisible, yet very tangible digital topography that is increasingly affecting our urban life. As W. J. Mitchell (Mitchell 2005) pointed out, the digital revolution has filled our world with “electronic instruments of displacement” that “embed the virtual in the physical, and weave it seamlessly into daily urban life”. The mobile phone, the most integrated mobile device is closely related to the notion of a digital identity, our personal identity on this digital space. The Bluetooth is the mainly used direct communication protocol between mobile phones today and in this scope, each device has its own unique ID, its “MAC address”. This paper investigates the potential use of recording and analysing Bluetooth enabled devices in the urban scale in understanding the interrelation between the physical and the digital topographies.

summary	Sustainable design and ecological building are the most significant global challenges for the design profession. To meet new building regulations and national targets for carbon emissions, all future buildings will be judged on their ‘green’ merits. For architects to maintain a competitive edge in a global market, innovation is now key; the design of new processes, technologies and materials that combat carbon emissions and improve the sustainable performance of buildings are paramount. Contemporary practices have responded by setting up multi- disciplinary internal research and development teams, with offices such as Foster + Partners, HOK and Aedas setting the bar for ground-breaking research and development. The aim of internal groups is often to adapt and create new technologies and materials and to borrow ways of working from other disciplines, to focus on innovation rather than incrementally increasing performance or efficiency. This title offers insights into how a wide range of established and emerging practices are rising to meet these challenges. In pursuit of integrated sustainability and low-energy building, material and formal innovation and new tools and technologies, it illustrates that the future of architecture is evolving in an exchange of ideas across disciplines. Incorporating the creation of new knowledge about ecological building within the profession, it also identifies the emergence of a collective will to seek out new routes that build in harmony with the environment.

title	Digital Form Finding: Generative use of simulation processes by architects in the early stages of the design process
doi	https://doi.org/10.52842/conf.ecaade.2011.107
source	RESPECTING FRAGILE PLACES [29th eCAADe Conference Proceedings / ISBN 978-9-4912070-1-3], University of Ljubljana, Faculty of Architecture (Slovenia) 21-24 September 2011, pp.107-115
summary	The paper presents performance oriented approaches to digital form finding which stems from the lines of research on performance and morphogenesis in architectural design. The main contribution to the earlier research is threefold; it examines the potential of the presented design processes to integrate interdisciplinary approach based on the use of simulation tools by architects or direct data exchange between simulation tools and design. Secondly, it explores new methods to generate initial architectural form based on performance information that apply to both building scale and urban scale, and lastly, it develops the theoretical framework on the ramifications of employing simulation technology and techniques in architectural design.

title	Agent-agent interaction as a component of agent-environment interaction in the modelling and analysis of pedestrian visual behaviour
doi	https://doi.org/10.52842/conf.caadria.2011.555
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 555-564
summary	This multidisciplinary project involves concepts from architectural design, statistical learning, machine vision, and human ecology. The focus is on analysing how pedestrians’ dynamic behaviour in space is influenced by the environmental design of different architectural scenarios. This paper presents a multi-agent pedestrian simulation and analysis system that supports agent-to-agent interactions, different spatial desires, and interpersonal distance. The system simulates and analyses pedestrian spatial behaviour with combined focus on movement trajectories, walking speed, and the visual gaze vector. The analysis component relies on learning a statistical model characterising normal/abnormal behaviour, based on sample observations of regular pedestrian movements without/with the impacts of significant visual attractions in the environment. Using the example of Wheeler Place in Newcastle (Australia) our pilot experiments demonstrate how pedestrian behaviour characteristics can depend on selected features in the visual environment. The presented system will allow architects and urban designers to obtain better assessment of planned urban spaces and streetscape characteristics and their impacts on pedestrian behaviour.

title	The backbone of a City Information Model (CIM): Implementing a spatial data model for urban design
doi	https://doi.org/10.52842/conf.ecaade.2011.143
source	RESPECTING FRAGILE PLACES [29th eCAADe Conference Proceedings / ISBN 978-9-4912070-1-3], University of Ljubljana, Faculty of Architecture (Slovenia) 21-24 September 2011, pp.143-151
summary	We have been witnessing an increased interest in a more holistic approach to urban design practice and education. In this paper we present a spatial data model for urban design that proposes the combination of urban environment feature classes with design process feature classes. This data model is implemented in a spatial database that becomes the backbone of a City Information Model (CIM), integrating urban neighbourhood formulation, design, and evaluation methods into a comprehensive urban design support system. We demonstrate its application to urban design analysis and evaluation through the development of a tool for AutoCAD Map 3D that is integrated with the PostGIS spatial database.

title	Digital catalogue: A computational implementation of Korean joinery system in the design of a transformable disaster shelter
doi	https://doi.org/10.52842/conf.caadria.2011.061
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 61-70
summary	With the help of Building Information Modelling (BIM), the digital catalogue of all the 44 components of Korean joinery system is developed for the application of their tectonic principles in the design of a transformable disaster shelter. Based upon the components of three primary bracket styles (Jusim-Po, Ik-Gong, and Da-Po) of traditional Korean joinery system in the catalogue, the parametric modifications of the components and their rearrangements are performed for various iteration of the disaster shelter. The usage of Korean joinery system in assembling and disassembling the components enhances the transformability and the reusability of the shelter. This paper demonstrates the computational implementation of Korean joinery system and the design process of a transformable disaster shelter.

summary	This paper reports on the initial findings of a long term case study. It focuses on the BIM implementation efforts for Brazilian public firms that are responsible for the design, construction and management of buildings, infrastructure and urban spaces. It was postulated that BIM implementation could bring to Brazilian public institutions benefits similar to the ones achieved in the US, yet at a different cost structure. Research follows a mixed methods approach using focus groups and quasi experiments. Results describe obstacles encountered, benefits realized, and process changes expected that result from Brazilian socio-cultural context applied to public institutions.

title	Data flow and processing in the computational fractal analysis method
doi	https://doi.org/10.52842/conf.caadria.2011.493
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 493-502
summary	One of the few quantitative methods available for the consistent analysis of architectural form is the ‘box-counting’ approach to determining the approximate fractal dimension of a plan or elevation. In its computational form this method has been used to analyze the plans and facades of a wide range of buildings. The data points produced are synthesized by the software into a series of fractal dimension (D) values that are in turn compiled in various ways to produce a series of composite results describing a complete building. Once this process is complete the data may be coded with additional information producing a set of mathematical results that describe the form of a building. This paper offers the first complete description of this important analytical process from the point of view of information flow, algorithmic operations, review options and data magnitude. No previous paper has detailed the full scope of the data used in the computational method, or the way in which various stages produce different types of outcomes. The purpose of this paper is to elucidate the way in which this particular computational method, drawing its inspiration from the complexity in natural systems, may be used to process different types of information and produce various forms of quantitative data to support architectural design and analysis.

title	An Urban Information Framework to support Planning, Decision-Making & Urban Design
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 653-668.
summary	This paper reports on a 2-year research project undertaken in collaboration with a state planning authority, a major city municipal council and a government-owned development organisation. The project has involved the design of an urban information model framework with the aim of supporting more informed urban planning by addressing the intersection where an individual building interfaces with its urban context. This adopted approach enables new techniques that better model the city and its processes in a transparent and accessible manner. The primary driver for this project was the challenge provided by the essential incompatibility between legacy GIS (geographic information system) datasets and BIM (building information model) representations of the built form. When dealing with urban scale information, GIS technologies use an overlay mapping metaphor linked to traditional relational database technologies to identify features or regions in the urban landscape and attach attribute data to those in order to permit analysis and informed assessment of the urban form. On the other hand, BIM technologies adopt an object-oriented approach to model the full three-dimensional characteristics of built forms in a way that captures both the geometric and physical attributes of the parts that make up a building, as well as the relationships between those parts and the spaces defined by the building fabric. The latter provides a far richer semantic structure to the data, while the former provides robust tools for a wide range of urban analyses. Both approaches are widely recognised as serving well the needs of their respective domains, but there is a widespread belief that we need to reconcile the two disparate approaches to modelling the real world. This project has sought to address that disjunction between modelling approaches. The UrbanIT project concentrated on two aspects of this issue: the development of a framework for managing information at the precinct and building level through the adoption of an object-oriented database technology that provides a platform for information management; and an exploration of ontology tools and how they can be adopted to facilitate semantic information queries across diverse data sources based on a common urban ontology. This paper is focussed on the first of those two agendas, examining the context of the work, the challenges addressed by the framework and the structure of our solution. A prototype implementation of the framework is illustrated through an urban precinct currently undergoing renewal and redevelopment, finishing with a discussion of future work that comes out of this project. Our approach to the implementation of the urban information model has been to propose extensions to ISO/PAS 16739, the international standard for modelling building information that is commonly known as IFC (Industry Foundation Classes). Our reason for adopting that approach is primarily our deep commitment to the adoption of open standards to facilitate the exchange of information across the built environment professions, but also because IFC is based on a robust object schema that can be used to construct a internet-accessible database able, theoretically, to handle the vast quantity of data needed to model urban-scale information. The database solution comes with well-established protocols for handling data security, integrity, versioning and transaction processing or querying. A central issue addressed through this work is concerned with level of detail. An urban information model permits a very precise and detailed representation of an urban precinct, while many planning analyses rely on simplified object representations. We will show that a key benefit of our approach is the ability to simultaneously maintain multiple representations of objects, making use of the concept of model view definitions to manage diverse analysis needs.

title	Sistema de seguimiento solar de bajo costo para instalaciones fotovoltaicas domésticas [Low-cost solar tracking system for domestic photovoltaic installations]
source	SIGraDi 2011 [Proceedings of the 15th Iberoamerican Congress of Digital Graphics] Argentina - Santa Fe 16-18 November 2011, pp. 118-122
summary	The ongoing research is focused on the development of a low-cost solar tracking system to improve domestic fixed PV installations which performance is dramatically diminished due to the absence of reorientation mechanisms to maximize solar energy capture. A straightforward way to reduce fabrication and maintenance costs of a domestic solar tracking system is to avoid the use of photoresistors. Most solar trackers use photoresistors to reorient their PV panels. However, the daily and seasonal solar path is well known and its variation is negligible when comparing photoresistorbased and preprogrammed reorientation against the amount of solar energy that is captured.

Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 110-115.
summary	Gottfried Semper, in his 1851 text The Four Elements of Architecture, famously classifies architecture into four elemental parts: the hearth, the roof, the enclosure, and the mound, describing the role of the last three to be the “defenders of the hearth’s flame against the three hostile elements of nature (Semper 2011).” Modernity has witnessed the role of enclosure evolve to that of a sealed envelope, or one which meticulously separates the ‘natural environment,’ from the internally regulated environment as part of modern comfort. The post-modern advent of the rain-screen has further separated the layer of exteriorized cultural expression from the structuring envelope, removing the ornamental aspect of Semper’s enclosure, from the enclosing layer. This habit of casting the natural processes out of our building envelopes has resulted in the rapid depletion of space for biodiversity within our cities. Joyce Hwang in her essay “Living Among Pests,” has suggested that the needed reconnection of biodiversity with our urban buildings will force a re-examination of “facade articulation to take on more responsibilities. Ornament will become performative” (Hwang 2013).

title	The social network virtual design studio: Integrated design learning using blended learning environments
doi	https://doi.org/10.52842/conf.caadria.2011.589
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 589-598
summary	Online communications, multimedia, mobile computing and face-to-face learning create blended learning environments to which some Virtual Design Studios (VDS) have reacted to. Social Networks (SN), as instruments for communication, have provided a potentially fruitful operative base for VDS. These technologies transfer communication, leadership, democratic interaction, teamwork, social engagement and responsibility away from the design tutors to the participants. The implementation of Social Network VDS (SNVDS) moved the VDS beyond its conventional realm and enabled students to develop architectural design that is embedded into a community of learners and expertise both online and offline. Problem-based learning (PBL) becomes an iterative and reflexive process facilitating deep learning. The paper discusses details of the SNVDS, its pedagogical implications to PBL, and presents how the SNVDS is successful in enabling architectural students to collaborate and communicate design proposals that integrate a variety of skills, deep learning, knowledge and construction with a rich learning experience.

title	Area cartograms in building product model visualization: A case study on the presentation of non-spatial object properties in spatial context with anamorphic maps
doi	https://doi.org/10.52842/conf.ecaade.2011.444
source	RESPECTING FRAGILE PLACES [29th eCAADe Conference Proceedings / ISBN 978-9-4912070-1-3], University of Ljubljana, Faculty of Architecture (Slovenia) 21-24 September 2011, pp.444-450
summary	Existing presentation of building information models is mostly based on a 1:1 mapping of spatial information to spatial visualisation parameters. This approach limits the presentability of non-spatial properties and can even produce misleading presentations. An area cartogram is a type of map where the size of the areas is tied to some non-spatial value instead of the real size of the object. We identified five types of cartograms, applied them to typical building geometry and evaluated the resulting presentations in terms of readability. Finally a use case scenario is given to prove the need of such formal studies and to provide the basis for further evaluation.

title	Digital forensics as a tool for augmenting historical architectural analysis: Case study: The student work of James Stirling
doi	https://doi.org/10.52842/conf.caadria.2011.505
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 505-514
summary	Digital techniques in architecture have developed rapidly over the last 25 years. This has enabled digitally mediated visualisations to become increasingly complex, and potentially more beneficial to the user. In architectural critique this creates an opportunity to reanalyse and re-interpret paper and photographic records of architectural artefacts. The information available to construct models of lost or unbuilt designs is almost always incomplete; therefore interpretation of material requires parallel study into the architect, their influences and the contemporary context they operated within. This can prove to be a rich exercise in augmenting a critical architectural analysis of an architect, a built product or building type. The process of constructing a model and its subsequent analysis can be referred to as scenario building, or informed extrapolation. This paper uses the reconstruction of an unbuilt scheme by Sir James Stirling as a vehicle to explore and illustrate the techniques, implications and limitations of the process.

summary	The paper explores how digital techniques can be applied to lost or unbuilt works of architecture in order to enhance our understanding of a particular architect or building they designed. For example, if current knowledge of a historic design is based on surviving literature or fragmented images, the new arrangement introduced using digitally augmented techniques allows a clearer reading of these original sources. Case study examples are used to demonstrate how this is achieved.

summary	As Hong Kong constructs increasingly high-density, high-rise public housing estates to increase land use efficiency, public in-between spaces are more constrained, which impacts the quality of social relations, movements and daily practices of residents (Shelton et al. 2011; Tang et al. 2019). Current planning practices are focused on the achievement of quantitative performance measures, rather than qualitative design considerations that support residents experiences and community interaction. This paper presents a new methodology that combines urban analysis and generative design for the regeneration of social housing estates, based on the spatial and social qualities of their in-between spaces.

source	Parametricism (SPC) ACADIA Regional 2011 Conference Proceedings
summary	Informal settlements consisting of substandard housing that lack adequate infrastructure, sanitation, living space and security, are one of the major challenges for developing cities in terms of their unpredictable growth. The colonias are informal settlements that originated in substandard housing development in the U.S. along the Mexico border. As informal settlements grow and transform into formal communities, their potential impacts upon energy consumption and economic development can be very high. This study proposes a method by using Building Information Modeling (BIM) parametric tool to develop a database of informal houses in the colonias that would assist the planning of development and upgrades.

summary	AUTOMATED COST ANALYSIS OF CONCEPT DESIGN BIM MODELS Interoperability: BIM models and cost models This paper introduces the automated cost analysis developed for the General Services Administration (GSA) and the analysis results of a case study involving a concept design courthouse BIM model. The purpose of this study is to investigate interoperability issues related to integrating design and analysis tools; specifically BIM models and cost models. Previous efforts to generate cost estimates from BIM models have focused on developing two necessary but disjoint processes: 1) extracting accurate quantity take off data from BIM models, and 2) manipulating cost analysis results to provide informative feedback. Some recent efforts involve developing detailed definitions, enhanced IFC-based formats and in-house standards for assemblies that encompass building models (e.g. US Corps of Engineers). Some commercial applications enhance the level of detail associated to BIM objects with assembly descriptions to produce lightweight BIM models that can be used by different applications for various purposes (e.g. Autodesk for design review, Navisworks for scheduling, Innovaya for visual estimating, etc.). This study suggests the integration of design and analysis tools by means of managing all building data in one shared repository accessible to multiple domains in the AEC industry (Eastman, 1999; Eastman et al., 2008; authors, 2010). Our approach aims at providing an integrated platform that incorporates a quantity take off extraction method from IFC models, a cost analysis model, and a comprehensive cost reporting scheme, using the Solibri Model Checker (SMC) development environment. Approach As part of the effort to improve the performance of federal buildings, GSA evaluates concept design alternatives based on their compliance with specific requirements, including cost analysis. Two basic challenges emerge in the process of automating cost analysis for BIM models: 1) At this early concept design stage, only minimal information is available to produce a reliable analysis, such as space names and areas, and building gross area, 2) design alternatives share a lot of programmatic requirements such as location, functional spaces and other data. It is thus crucial to integrate other factors that contribute to substantial cost differences such as perimeter, and exterior wall and roof areas. These are extracted from BIM models using IFC data and input through XML into the Parametric Cost Engineering System (PACES, 2010) software to generate cost analysis reports. PACES uses this limited dataset at a conceptual stage and RSMeans (2010) data to infer cost assemblies at different levels of detail. Functionalities Cost model import module The cost model import module has three main functionalities: generating the input dataset necessary for the cost model, performing a semantic mapping between building type specific names and name aggregation structures in PACES known as functional space areas (FSAs), and managing cost data external to the BIM model, such as location and construction duration. The module computes building data such as footprint, gross area, perimeter, external wall and roof area and building space areas. This data is generated through SMC in the form of an XML file and imported into PACES. Reporting module The reporting module uses the cost report generated by PACES to develop a comprehensive report in the form of an excel spreadsheet. This report consists of a systems-elemental estimate that shows the main systems of the building in terms of UniFormat categories, escalation, markups, overhead and conditions, a UniFormat Level III report, and a cost breakdown that provides a summary of material, equipment, labor and total costs. Building parameters are integrated in the report to provide insight on the variations among design alternatives.
